Description

Technical Field

[0001] This utility model relates to the technical field of fluid distribution and filtration equipment, specifically to a central water distribution pipe. Background Technology

[0002] Water treatment technology is a core process in modern resource purification, seawater desalination, and wastewater recycling. As the pressure vessel of the system, the membrane housing's central water distribution pipe determines the efficiency and output quality of the water treatment system. This central water distribution pipe serves the dual function of evenly distributing high-pressure raw water and collecting the purified water produced by the membrane elements. Its design quality directly affects the uniformity of water flow, the fouling rate of the membrane elements, the system's energy consumption, and the final quality of the produced water.

[0003] Currently, the central distribution pipes widely used in the industry are mostly made of PVC pipes through secondary machining, which has many inherent defects. First, the traditional drilling process (such as drilling) lacks standardization, resulting in low production efficiency and producing plastic shavings inside the holes that are difficult to clean completely. These impurities can enter the membrane elements during system operation, easily causing irreversible membrane fouling and damage. Second, the distribution of drill holes often relies on experience, making it difficult to achieve precise and uniform circumferential and axial arrangement. This easily leads to uneven water flow distribution, with some membrane elements being overloaded and quickly fouled, while others are underutilized, resulting in a decrease in the overall system's water production efficiency. In addition, the central distribution pipe lacks a flow regulation mechanism. These problems restrict further improvement of membrane system performance and stable operation.

[0004] Therefore, how to provide a central water distribution pipe that overcomes the defects of the existing structure is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides a central water distribution pipe to solve the problems of uneven water flow, reduced system efficiency, and lack of flow regulation mechanism caused by insufficient standardization of the drilling process and uneven hole distribution in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a central water distribution pipe, comprising: The tube has a connector installed at one end and a connecting groove on the inner wall of the other end. Several transverse holes are formed on the wall of the tube body, and the transverse holes penetrate the inner and outer walls of the tube body. A sleeve is rotatably connected inside the tube body, and a through groove corresponding to the transverse hole is provided on the sleeve.

[0007] In one possible implementation, the transverse holes are evenly distributed circumferentially along the central axis of the tube on a horizontal plane, and are evenly distributed vertically along the axial direction of the tube.

[0008] In one possible implementation, the inner edge of the transverse hole is chamfered.

[0009] In one possible implementation, the chamfer has an angle α between it and the horizontal plane, where 30°≤α≤60°.

[0010] In one possible implementation, an annular groove is formed on the inner wall of the tube, and the annular groove is engaged with the sleeve.

[0011] In one possible implementation, the sleeve includes: The sleeve body has a limiting block installed on its outer wall, and the limiting block is engaged with the annular groove. A slot is provided at one end of the sleeve body, and a plug is installed at the other end of the sleeve body. Two adjacent sleeve bodies are connected to the slot by the plug.

[0012] This invention breaks down traditional long pipes into short pipe segments connected by interference fits between connectors and connecting grooves, improving the convenience of transportation and installation. Its core advantages are: First, the evenly arranged horizontal holes ensure uniform water distribution and collection, significantly improving the efficiency of the water treatment system and the lifespan of the membrane housing. Second, the rotatable sleeve nested within the pipe body allows for adjustment of the water flow rate by adjusting the overlap between the through groove and the horizontal holes. Furthermore, the interlocking blocks and slots between adjacent central water distribution pipes achieve linkage, enabling simultaneous flow rate adjustment of the connected central water distribution pipes. This invention offers multiple advantages, including pre-set hole groups to prevent burr contamination, uniform water distribution, and reliable connections. Attached Figure Description

Detailed Implementation

[0016] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please refer to Figures 1-5 The present invention will now describe a central water distribution pipe, as follows: Figures 1-4 It includes a pipe body 1, a connector 2, a connecting groove 3, a horizontal hole 4, a sleeve 5, and a through groove 6. The connector 2 is installed at one end of the pipe body 1, and the connecting groove 3 is opened on the inner wall of the other end of the pipe body 1. Several horizontal holes 4 are opened on the pipe wall of the pipe body 1. The horizontal holes 4 pass through the inner and outer walls of the pipe body 1. The sleeve 5 is rotatably connected to the inside of the pipe body 1. The through groove 6 corresponding to the horizontal hole 4 is opened on the sleeve 5.

[0018] The usage process of this utility model embodiment is as follows: First, the required number of central water distribution pipes is calculated based on the length of the membrane shell. These central water distribution pipes have been prefabricated with complete sets of four horizontal holes and inner chamfers 41 through an integrated injection molding process, fundamentally avoiding lint contamination caused by on-site drilling. Subsequently, the central water distribution pipes are spliced ​​together through the connectors 2 and connecting grooves 3 provided at both ends of the pipe body 1. At the same time, the inserts at the lower ends of each sleeve 5 are also inserted into the slots of the adjacent sleeve 5, so that the inside of the pipe body 1 is also connected into a whole synchronous water flow regulating mechanism. This allows multiple central water distribution pipes to be assembled into a continuous pipeline. Once installed, when the water flow needs to be adjusted, simply rotate any one section of the sleeve 5 with a tool. The linked structure will then drive all the sleeves 5 to rotate synchronously, causing the through groove 6 on the sleeve 5 to shift relative to the horizontal hole 4 on the pipe body 1. This changes the overlapping area, thereby adjusting the water flow. When water is supplied after assembly, the water seeps out from the evenly distributed horizontal holes 4 on the pipe body 1. This design avoids the problems of cleaning debris and clogging caused by uneven hole distribution during on-site drilling in traditional processes. Furthermore, the chamfer 41 on the inner edge of the horizontal hole 4 further optimizes the water flow, reduces water turbulence and impurity accumulation, and ensures the efficient and reliable operation of the system.

[0019] In one specific embodiment, the horizontal holes 4 are evenly distributed circumferentially along the central axis of the pipe body 1 on the horizontal plane, and evenly distributed vertically along the axial direction of the pipe body 1. The horizontal holes 4 are uniformly prefabricated on the circumferential and axial walls of the pipe body 1 through integral molding, fundamentally solving the technical drawback of uneven distribution of traditional central pipe holes. This hole design ensures consistent water output in any radial and axial direction.

[0020] In a specific embodiment, such as Figure 5 The inner edge of the horizontal hole 4 is chamfered 41. This design, by forming a smooth chamfer on the production mold, completely eliminates the burrs that inevitably occur during traditional on-site mechanical drilling, ensuring the cleanliness and smooth flow of the pipe interior. At the same time, the chamfer structure also plays a role in assisting flow guidance, reducing water resistance, and further improving seepage efficiency.

[0021] In a specific embodiment, such as Figure 6 The chamfer 41 has an included angle α with the horizontal plane, where 30°≤α≤60°. This design ensures that the chamfer structure has sufficient openness to guide water flow and reduces the risk of impurities accumulating and clogging at the orifice, while also preventing the guiding effect from decreasing due to an excessively large angle. This angle range provides a standard guiding angle for water flow, reducing orifice resistance and promoting stable water diffusion, thereby reducing the adhesion and accumulation of impurities at the orifice.

[0022] In a specific embodiment, such as Figures 2-3The inner wall of the pipe body 1 is provided with an annular groove 12, which engages with the sleeve 5. In this embodiment, the annular groove 12 is set on the inner wall of the upper and lower ends of the pipe body 1. The annular groove 12 is an annular groove machined on the inner wall of the pipe body 1. Its function is to engage with the limiting block 56 on the sleeve 5. Because of the annular groove design with the ends connected, the limiting block 56 can slide inside it, that is, the sleeve 5 can rotate circumferentially around its axis inside the pipe body 1, thereby realizing flow regulation. It can also stably restrict the sleeve 5 inside the pipe body 1, so that it will not undergo relative displacement in the center of gravity direction.

[0023] In a specific embodiment, such as Figures 2-4 The sleeve 5 includes a sleeve body 51, a slot 53, a plug 54, and a limiting block 55. A limiting block 55 is installed on the outer wall of the sleeve body 51, and the limiting block 55 engages with the annular groove 12. The slot 53 is located at one end of the sleeve body 51, and the plug 54 is installed at the other end of the sleeve body 51. Two adjacent sleeve bodies 51 are connected by the plug 54 and the slot 53. In this embodiment, two limiting blocks 55 are provided, and their positions correspond to the annular groove 12. The sleeve body 51 serves as the support structure for the entire mechanism, and the through groove 6 on it is the outlet for controlling the water flow. The limiting block 56 on the outer wall of the sleeve body 51 engages with the annular groove 12 of the pipe body 1, ensuring that the sleeve 5 can rotate smoothly within the pipe body 1 without causing relative displacement in the direction of the center of gravity. When multiple central water distribution pipes are connected together, the sleeves 5 inside the two adjacent central water distribution pipes engage with each other through slots 53 and inserts 54. When one sleeve 5 rotates, the insert 53 pushes the adjacent slot 54, transferring the force to the next sleeve 5. This design ensures that the through slots 6 on the sleeves 5 maintain a consistent angle, thereby achieving consistent overall flow rate adjustment.

[0024] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
